Power Specs Input 100V-240V 50/60Hz; Output: 12V 3A 36W. Output adaptor Self-Adapting Barrel jack size: 5.5mm x 2.1mm (applicable 2.5mm) positive (+) center,Cord Length: 1.5m (about 4.9ft); Intelligent Identification Output The adapter can automatically identify the current amperage required by the electronic device. For example; 50ma 100ma 150ma 200ma 800ma 900ma 1000ma 2000ma 3000mA he highest output is 3A. Extensive Compatibility Suitable for CCTV Cameras, LED Strip light, led tape light, keyboard, BT speakers, GPS, webcam, router, and more 12V electronics. The products adopt the industry's top materials and processes, flame retardant shell resistant to high temperature of 1382℉, premium-quality components and safe&reliable power cord. Be Careful. (1) This product is an AC to DC adapter, NOT A CHARGER!!! It cannot be used to charge electronic devices with batteries, such as laptops. Otherwise, it may damage your device. (2) Never overload. If the current drawn exceeds 3A, the power supply will be damaged soon. (3) The polarity is inside positive (+) and outside negative (-). They cannot be wrongly connected. (4) Indoor use only.

Is this DC 12V 3A power supply compatible with your device?
1)Check the voltage. It only fits 12V appliances
2) Check the current. The current your device needs must be equal to or less than 3A,such as 200mA 300mA 400mA 500mA 650mA 850mA 700mA 900mA 1000mA 1200mA 2000mA 3000mA
3) Check the power input port of your device. Its outer diameter should be 5.5mm; inner core diameter should be 2.1-2.5mm. Inner core polarity should be"+", exterior polarity should be" - "
